  Backlit colour graphic problem, help needed please?

  Posted by Warren Beard on 26 February 2008 at 20:15

  Hi Guys

  A customer of mine has had a graphic applied to a lightbox and the black areas are glowing a dirty green colour. Any ideas why the black would look green and a way to resolve the problem?

  Cheers

  Because ink is not opaque. if it was printed black (inkjet) then the light would show through.

  I’m not sure what ink it was printed with or any details at all, all I was told and shown was a picture with the dark shadow areas looking green when they should be black. Not sure how it would be green 😕

  I was hoping somebody might have experienced this before and could shed some light on it 😉

  cheers

  perhaps it was printed as rgb black or just K, they could have a greenish tint when back lit.
  I could be wrong, but only going on my limited experience of print.

  awaiting the experts….

  thats the problem some one switched it on.

  i can understand the problem might be wrong so my guess is that the printer needs a different profile and or media, even the file may be poor colour.

  i have done a few and needs care and thought
